UNITED STATES PATENT OFFICE JAMES DODGE, OF NEWARK, NEW JERSEY.

MACHINE FOR MAKING CLAW-ENDS OF HAMMERS.

SPECIFICATION forming part of Letters Patent No. 326,632, dated September 22, 1885.

Application filed October 25, 1884.

To all whom, it may concern:

Be it known that I, JAMES DODGE, of the city of Newark, county ofEsseX, and State of New Jersey, have invented a new and useful Machine and Appliances for Rolling, Forming, and Making the Claw-Ends of Carpenters Nail and Farriers Driving Hammers, of which the following is a specification.

The machine and appliances consist of two rolls mounted in proper housings and suitably geared for driving the same, these rolls, or, by preference, dies upon the rolls, consisting of half-circles or segments. One of these segments has two matrices cut into it to give the desired form to the claw. The other one, its mate, has two recesses formed for the purpose of inserting in each a knife, so that they will be, when in working position, in the center of the corresponding matrices, the knives being for the purpose of dividing the claws into two equal parts.

In order to make known more fully and eX- actly the several parts of my invention, I will describe it particularly, reference being had to the accompanying drawings, Figures 1 and 2, and to the letters of reference marked thereon. i

Fig. 1 is a front elevation of the described machine. Fig. 2 is a cross section of the same.

A A are the rolls. B B are the dies or segments, and O O are the nuts and collars holding the segments or dies to the rolls. D D are two feathers or keys sunk into the rolls to prevent the die from turning around on the same.

(No model.)

The hammer-blanks may be formed by the usual process, in which the claw-ends are left unfinished.

By preference the rolls have a stop-motion, so that on each turn they come to a stand still. The segments or dies are at this point sufficiently far from the center to allow an opening between the matrices and the knives for the insertion of the unfinished end of the hammer. The unfinished blank is put into matrix E, Fig. 1, and the knife F partly divides, and the matrix Epartly forms, the claws,which are next inserted into the matrix E", and the knife F fully divides the claw, and the matrix E gives it the finishing form.

Having now fully described my invention, I want it understood that I do not claim the rolls nor the stop-motion; but

What I do claim is The formation of the matrices in the face of the roll,or, by preference, the dies thereon, for the purpose of forming the claw-ends of hammers, and the knives for splitting and dividing the same, substantially as described and shown.

In witness whereof Ihave hereunto set my signature in the presence of two witnesses.

JAMES DODGE.
